What is the role of nonstop bridging (NSB) in relation to graceful restart?

NSB is used to synchronize routing tables between the primary and backup routing engines

NSB provides a backup for routing protocols that do not support GR

NSB ensures that Layer 2 forwarding continues during a control plane restart

NSB is only used on switches that do not support routing

Which benefit does graceful restart provide in a network that uses routing protocols?

It provides a backup routing protocol in case the primary protocol fails

It eliminates the need for routing protocol authentication

It ensures that routing protocol adjacencies are not torn down during a control plane restart

It reduces the number of routing protocol updates sent between neighbors

Which configuration statement enables graceful restart for LDP on Junos?

set protocols mpls graceful-restart

set protocols ldp restart-duration 300

set protocols ldp graceful-restart

A service provider is implementing BGP graceful restart on its route reflectors. The route reflectors have many BGP peers, and the provider wants to ensure that during a route reflector restart, the forwarding tables of the clients remain intact and BGP sessions are not reset. What must be configured on the BGP peers to support this?

The BGP graceful restart capability in the BGP open message

The BGP multiprotocol extensions capability

The BGP route refresh capability

A network engineer is configuring LDP graceful restart on a router that will act as a restarting router. The engineer wants to ensure that the router can signal its restart to neighbors and preserve label bindings. What must be configured on the restarting router?

LDP graceful restart with the restart-time and recovery-time timers
